The Sampling Process
Trend Analysis
 A
single sampling analysis is useful in providing information when
critical failure conditions exist. However, trend analysis is a
better tool for estimating the useful life or overall condition of
your engine or equipment. Trend analysis samples are taken and
analyzed at regularly scheduled intervals. Comparing the most recent
analysis to previous reports on a given machine shows the
development of trends. Monitoring these trends enables early
detection of internal abnormalities. Tested values falling within
acceptable limits may show a pattern of subtle variance, which could
signal a developing problem.
Machines of
the same type will accumulate contaminants and wear at different
rates. Performing trend analysis on each machine is the most
effective method of giving you an internal look at your equipment
and enabling you to deal with developing problems before they become
catastrophic situations.
Sampling Frequency
The frequency of sample analysis from your equipment depends on the
machine type, machine application and condition, operating
environment and other variables. For example, many machines that
operate in harsh environments, such as heavy equipment in mining or
construction, require short oil sampling intervals - every 100 to
300 operating hours. However, certain power transmission systems,
such as gearboxes and hydraulic systems used inside manufacturing
and production facilities, require no more than quarterly sampling
intervals. The following table lists generic sampling frequencies
for common equipment types, and is provided as a guideline only.

Collecting a
clean and representative oil sample is critical to the oil analysis
process. Put simply, an oil analysis is only as good as the sample
taken. The accuracy and reliability of the data produced by an
analysis hinges on receiving a representative sample from the
equipment to be tested. To assure that the sample extracted is
representative of the system, always follow proper sampling
procedures.
